7 HAI DRIVIS 350 MILES IN 4 1/2 HOURS. HOW FAST WAS HE GOING IN MIES PER HOUR?
1 answer:
Answer:
77.78 mph
Step-by-step explanation:
[1] So we know that someone is driving 350 miles and it takes / took them 4 1/2 hours. I am going to change 4 1/2 to 4.5 for the sake of making it easier.
[2] Miles per hour, is, as it says, miles per hour. Aka, (your time is almost always on the bottom / the y)
[3] So, that being said, to solve you will but 350 over 4.5 like this: which calcuates to arounddd 77.78!
(I hope this is correct, I was slightly confused by the wording. Have a nice day!)

Answer:
solution given:
principal [P]=$850
time[T]=8years
rate[R]=8%
now
simple interest [S.I.]= =$
=$544
so
Total balance=S.I.+P=$544+$850=$1394.
